A gift to myself, These pjs are as light as a feather! The material is that of a handkerchief and they even get comfier as they're washed. (In cold as the label instructs). Being 100% cotton, keep in mind, they don't have "give" as with Carol Wright poly/cotton pjs - for this reason, I went with the 1x - (similar Carol Wright poly/cotton pjs, I wear large). I am 5'6", 180 & pretty well-endowed (if anyone is wondering what size to order). Pretty, soft, lightweight & wash beautifully. I am a very restless sleeper - for this reason, I avoided pjs for years, but these don't bunch at all! I LOVE them and I'm sure you will too =)
